“The real purpose of the scientific method is to make sure Nature hasn't misled you into thinking you know something you don't actually know. There's not a mechanic or scientist or technician alive who hasn't suffered from that one so much that he's not instinctively on guard. That's the main reason why so much scientific and mechanical information sounds so dull and so cautious. If you get careless or go romanticizing scientific information, give it a flourish here and there, Nature will soon make a complete fool out of you. It does it often enough anyway even when you don't give it opportunities. One must be extremely careful and rigidly logical when dealing with Nature: one logical slip and an entire scientific edifice comes tumbling down. One false deduction about the machine and you can get hung up indefinitely.”

“What’s emerging from the pattern of my own life is the for belief that the crisis is being caused by the inadequacy of existing forms of thought to cope with the situation. It can’t be solved by rational means because the rationality itself is the source of the problem. The only ones who’re solving it are solving it at a personal level by abandoning ‘square’ rationality altogether and going by feelings alone. Like John and Sylvia here. And millions of others like them. And that seems like a wrong direction too. So I guess what I’m trying to say is that the solution to the problem isn’t that you abandon rationality but that you expand the nature of rationality so that it’s capable of coming up with a solution.”

“To live for some future goal is shallow. It's the sides of the mountain that sustain life, not the top.”

“Even in the presence of others he was completely alone.”

“If you run from technology, it will chase you.”

“The study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself. Working on a motorcycle, working well, caring, is to become part of a process, to achieve an inner peace of mind. The motorcycle is primarily a mental phenomenon.”

“Boredom always precedes a period of great creativity.”

“Traditional scientific method has always been at the very best, 20 - 20 hindsight. It's good for seeing where you've been. It's good for testing the truth of what you think you know, but it can't tell you where you ought to go.”

“Quality is a direct experience independent of and prior to intellectual abstractions.”

“We do need a return to individual integrity, self-reliance, and old-fashioned gumption. We really do.”

“The place to improve the world is first in one's own heart and head and hands.”
